Well, if you've got all that already then I'm not sure why you even need to be looking at my mapping page
Until I looked at it I didn't know that know that I didn't need to look at it. I had hoped that you might have got onto a more recent and complete data source than I have.
- though I'm not sure how accurate the data on the Internet Stellar Database is (does it use the new reduction of Hipparcos?)ISDB
is a collation of data from different sources, with the source separately noted for each datum. For example, the source for the parallax for Sirius (first thing I thought to check) is noted as "Hipparcos". For what it's worth it lists the position of each star three times: once as right ascension, declination, and distance, once in "celestial" (i.e. equatorial) X, Y, and Z, and once in "galactic" X, Y, and Z. But these aren't stored separately in the database, the conversions are done on the fly by the query script. (I note that it has defined galactic co-ordinates slightly differently from you.)
For anybody who might be interested, here is a picture showing the Galaxy projected onto the base plane of the "galactic" co-ordinate system
. For what it is worth, my entire setting is mostly confined to the little white circle labelled "Sun".
